roses, lilies, dahlias, chrysanthemums, and many other 

 varieties of horticultural plants. The types of trees, 

 shrubs and flowering plants that are not hardy in this 

 climate are shown in two large greenhouses: Conserva- 

 tory Range Number I, on the western side of the Garden, 

 covering about one acre and divided into fifteen com- 

 partments; and the somewhat smaller and still uncom- 

 pleted Conservatory Range Number 2, on the northeastern 

 side, comprising twelve compartments. These houses 

 offer a considerable range of temperature and moisture 

 conditions and contain large collections of temperate, 

 desert, subtropical and tropical plants, such as orchids, 

 ferns, cycads, pitcher plants, century plants, begonias, 

 bananas, cactuses, palms, aroids, bromeliads, and water- 

 lilies and other aquatic plants. Some 15,000 different 

 species and rarities of all kinds of plants are now 

 represented.

 The museum contains three collections: fossil plants,
